Seeing it here too. On our 4-byte capable routers: 91.196.186.0/24 *[BGP/170] 1d 13:36:53, MED 0, localpref 105, from 193.75.0.204 AS path: 16150 15703 43531 AS_TRANS I AS path: 3356 6461 15703 43531 AS_TRANS I AS path: 1299 3549 15703 43531 AS_TRANS I And on our non 4-byte capable routers it is simply shown as 23456. This ASN should not be used to originate prefixes, agreed. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
